Fermented cabbage, also known as kraut (5 letters), is a traditional food that has been around for centuries. It is made by salting and fermenting cabbage, which gives it a unique flavor and texture. Kraut is often served as a side dish or as an ingredient in many dishes, such as sauerkraut soup and sauerkraut pierogi. It is also a popular topping for hot dogs and hamburgers. Kraut is a great source of probiotics, which can help improve digestion and boost the immune system.
